System User's Guide: Operating System and Devices
The pr command performs
simple formatting of the files you sent to be printed. Pipe the output
of the pr command to the qprt command to format your
text.
Some useful pr command
flags are:
| -d
| Double-spaces the output.
|
| -h
"String"
| Displays the specified string, enclosed in quotation marks ("
"), instead of the file name as the page header. The flag and
string should be separated by a space.
|
| -l Lines
| Overrides the 66-line default and resets the page length to the number of
lines specified by the Lines variable. If the
Lines value is smaller than the sum of both the header and trailer
depths (in lines), the header and trailer are suppressed (as if the
-t flag were in effect).
|
| -m
| Merges files. Standard output is formatted so that the
pr command writes one line from each file specified by a
File variable, side by side into text columns of equal fixed
widths, based on the number of column positions. This flag should not
be used with the -Column flag.
|
| -n
[Width][Character]
| Provides line numbering based on the number of digits specified by the
Width variable. The default is 5 digits. If the
Character (any non-digit character) variable is specified, it is
appended to the line number to separate it from what follows on the
line. The default character separator is the ASCII TAB
character.
|
| -o Offset
| Indents each line by the number of character positions specified by the
Offset variable. The total number of character positions per
line is the sum of the width and offset. The default value of
Offset is 0.
|
| -sCharacter
| Separates columns by the single character specified by the
Character variable instead of by the appropriate number of
spaces. The default value for Character is an ASCII TAB
character.
|
| -t
| Does not display the five-line identifying header and the five-line
footer. Stops after the last line of each file without spacing to the
end of the page.
|
| -w Width
| Sets the number of column positions per line to the value specified by
the Width variable. The default value is 72 for equal-width
multicolumn output. There is no limit otherwise. If the
-w flag is not specified and the -s flag is specified,
the default width is 512 column positions.
|
| -Column
| Sets the number of columns to the value specified by the
Column variable. The default value is 1. This option
should not be used with the -m flag. The -e and
-i flags are assumed for multicolumn output. A text column
should never exceed the length of the page (see the -l
flag). When this flag is used with the -t flag, use the
minimum number of lines to write the output.
|
| +Page
| Begins the display with the page number specified by the Page
variable. The default value is 1.

For example, to print a file named
prog.c with headings and page numbers on the printer,
type:
pr prog.c | qprt
Press Enter.
This adds page headings to
prog.c and sends it to the qprt command.
The heading consists of the date the file was last modified, the file name,
and the page number.
For example, to specify a title
for a file named prog.c , type:
pr -h "MAIN PROGRAM" prog.c | qprt
Press Enter.
This prints
prog.c with the title MAIN PROGRAM in place of
the file name. The modification date and page number are still
printed.
For example, to print a file named
word.lst in multiple columns, type:
pr -3 word.lst | qprt
Press Enter.
This prints the
word.lst file in three vertical columns.
For example, to print several
files side by side on the paper:
pr -m -h "Members and Visitors" member.lst visitor.lst | qprt
This prints
member.lst and visitor.lst side by side with
the title Members and Visitors.
For example, to modify a file
named prog.c for later use, type:
pr -t -e prog.c > prog.notab.c
Press Enter.
This replaces tab characters in
prog.c with spaces and puts the result in
prog.notab.c. Tab positions are at columns 9,
17, 25, 33, and so on. The -e flag tells the pr
command to replace the tab characters; the -t flag suppresses
the page headings.
For example, to print a file named
myfile in two columns, in landscape, and in 7-point text,
type:
pr -l66 -w172 -2 myfile | qprt -z1 -p7
Press Enter.
See the pr command in the AIX 5L Version 5.1
Commands Reference for the exact syntax.
